This tool is intentionally explicit about DOM/DOW semantics. Real schedulers can differ; always verify in the runtime that will execute the job.

This visualizer models a simplified cron behavior and runs entirely in your browser. Always validate critical schedules against the cron implementation used by your infrastructure (Linux crond, Quartz, Kubernetes, serverless platforms, etc.).
